Abstract (en)

[origin: WO9914624A1] The invention relates to an optical transmitter for emitting light signals, especially for simultaneously activating light signal receivers present within a spatial range. Said optical transmitter has a laser diode (10) and an optical transmitting system. Said laser diode (10) emits an especially pulsed, concentrated laser beam (14). The optical transmitting system has a Fresnel mirror (12) and a primary mirror (15) whose convex mirror surface (151) is turned towards the mirror surfaces (121) of the Fresnel mirror (12). This enables the transmitter to illuminate as large a solid angle as possible, and gives a compact, robust structure. The laser diode (10) is located in the centre of the Fresnel mirror (12), coaxial to the axis of the Fresnel mirror (12) and the primary mirror (15) in the direction of emission (13) of the laser diode (10) and at a distance in front of and coaxial to the exit aperture (11).
